Embodiment 1

[0029] like figure 1 , the present invention includes a fish reef body 1, which is characterized in that the fish reef body 1 includes a hollow terrace structure of a top panel 2, a side panel 3 and a bottom panel 4, and the top panel 2 and the side panels 3 are all provided with openings 5. The openings 5 ​​are provided with juvenile fish screening devices 6 for screening juvenile fish. The top panel 2 of the fish reef body 1 is a square with a side length of 1m; the bottom panel 4 is a square with a side length of 3m; the reef height of the fish reef body 1 is 1m and the wall thickness is 10cm. The angle of inclination of the side panel 3 is 45°, so that the juvenile fish can pass through the juvenile fish screening device 6 smoothly. The opening 5 of the side panel 3 is located at the center, and the size of the opening 5 is 60cm×85cm. The size of the opening 5 of the top panel 2 is 50cm×50cm, which can ensure the light inside the reef body, facilitate the growth of algae...

Abstract

The invention relates to an enhancement-type artificial fish reef device for protecting and promoting the growth of juvenile fish. The enhancement-type artificial fish reef device comprises a fish reef body, and is characterized in that the fish reef body is of a hollow truncated pyramid structure and comprises a top panel, a bottom panel and side panels; the top panel and the side panels are provided with juvenile fish screening devices for fish to enter the fish reef body to hide from enemies, and the juvenile fish screening devices are composed of frames fixed to openings, grid bars fixed to the frames and made of magnetic materials, and artificial seaweed wrapping the grid bars in a winding mode; a juvenile fish nutrition device is hung on the top panel of the fish reef body, and crabshell powder is contained in the juvenile fish nutrition device and can improve the immunity of the juvenile fish, promote the growth of juvenile fish and reduce the death rate of juvenile fish; algaadherence matrixes are arranged on the outer sides of the side panels of the fish reef body, and oyster shells and gravel are contained in the fish reef body and can increase the adherence area of algae, promote the reproduction of algae and further provide adequate bait for juvenile fish. The enhancement-type artificial fish reef device is low in cost, simple in structure and long in service life, and the survival rate of juvenile fish is increased to achieve the enhancement of fishery resources.

Description

technical field [0001] The invention belongs to marine fishery engineering facilities, in particular to a multiplication type artificial fish reef device for protecting and promoting the growth of juvenile fish. Background technique [0002] Due to overfishing, environmental pollution, and global climate change, offshore fishery resources are exhausted. Artificial reefs, as an important means of restoring the marine ecological environment and protecting marine biological resources, have become a research hotspot around the world. However, there are still many deficiencies in the construction of artificial reefs. The existing artificial reefs only provide suitable habitats and breeding places for fish and other marine organisms, so as to achieve the purpose of restoring fishery resources. However, the fish reefs that have damaged fishery resources have not been repaired through the protection of juvenile fish and the improvement of the survival rate of juvenile fish. The re...
